The reasons why there are two trademarks on one piece of clothing may be as follows:

1. Business strategy needs: Enterprises sometimes use the form of primary and secondary trademarks for commercial operations. , the main trademark is usually used for core products or brands, while the sub-trademark is used for new products or models. This can take advantage of the popularity of the main trademark and make it easier for consumers to accept and recognize the goods using the sub-trademark.

2. Legal provisions: Although the "Trademark Law" and the "Trademark Law Implementation Regulations" do not clearly stipulate that more than two registered trademarks cannot be used on one product, but the use of more than two registered trademarks Trademarks should comply with legal provisions and must not infringe on the intellectual property rights of others.

Please note that specific trademark usage strategies need to be based on actual circumstances. You can consult relevant business people to understand the reasons.
